Potato is a root in it storage of food has taken place.

Sikandar.k said: (Sep 4, 2011)  
Potato is a root so I m unable to understand how the answer is stam. Please specify.

Sambasiva said: (Nov 18, 2011)  
Potatoes are occasionally referred to as a root crop because we eat a part of the plant that grows underground. However, the part of the potato that is eaten is not a root, it is actually a specialized stem called a tuber.

Whereas the sweet potato is different. It is modified root.

Bemcha said: (Dec 24, 2011)  
Potato has nodes and internodes which is a characteristic of stem so the answer is correct.

Priyanka said: (Sep 4, 2012)  
Yes, potatoes though they stored food it has nodes and inter nodes which are the characteristics of stems so potato included under stem some stems also store food e. G ginger also stem but it store food.

Janvi Patel said: (Dec 27, 2013)  
No the answer is correct. Potatoes are stems as they even have nodes and Internodes. And foolishly even grows underground.

Khushahal Vijay said: (Jun 19, 2014)  
But I think potato is a root so I am unable to understand why the answer is root please specify.

Nsyadav said: (Dec 23, 2014)  
It is a stem because characteristic of stem such as bud node are seen in potato. It store a food like sugar cane.

Pragnya said: (Feb 7, 2015)  
Potato is an example for stem tuber. It is a kind of stem modification in which lower part of the stem grows into soil. The apices of these underground branches stores food materials and becomes tuberous.

Caroline said: (Mar 20, 2015)  
Potato are stem tubers. Enlarged stolons thicken to develop into storage organs. The tuber has all the parts of a normal stem, including nodes and inter nodes. The nodes are the eyes and each has a leaf scar. The nodes or eyes are arranged around the tuber in a spiral fashion beginning on the end opposite the attachment point to the stolon.

The terminal bud is produced at the farthest point away from the stolon attachment and tubers thus show the same apical dominance as a normal stem. Internally, a tuber is filled with starch stored in enlarged parenchyma like cells. The inside of a tuber has the typical cell structures of any stem, including a pith, vascular zones, and a cortex.

K.ANJALI said: (Sep 21, 2015)  
Potato have roots on it so it is root based fruit.

Jannat said: (Nov 16, 2015)  
Potato is a modification of root. Sweet potato is the modification of stem. Both of them are analogous to each other.

Raghavendra G H said: (Mar 24, 2016)  
Potato is a root, so I am unable to understand how the answer is the stem. Please specify.

Dr. Gilbert Bentley said: (Mar 25, 2016)  
The correct answer is the stem, because we can nodes and inter nodes in potato which is a characteristic of stem.

Meghana Sadha said: (Mar 27, 2016)  
Potato is a modified stem because it consists of nodes and internodes.

Kiran said: (Jun 23, 2016)  
Kiran: I am unable to understand how is the answer is 'stem'. Please explain the reason.

Rhythm said: (Aug 19, 2016)  
What is potato node and internode?

Selam said: (Aug 26, 2016)  
How could it be stem? The Answer is root.

R.Sumanth said: (Aug 27, 2016)  
Yes, the potato is also called solanum tuberosum it is swallen apex of the underground branch.

Why is a sugarcane plant not called a stem tuber yet it stores its food in the stem?

Why is a sugarcane plant not called a stem tuber yet it stores its food in the stem?

Kowsi said: (May 28, 2017)  
1. The stem is normally divided into nodes and inter nodes.
2. Lateral buds and leaves grow out of stem at intervals called nodes.
3. The intervals on the stem between the nodes are called internodes.
4. The number of leaves that appear only at a node depends on the species of plant.

Lesponi Pradhan said: (Jul 7, 2017)  
Potato is modified term of stem. It is also called splanum tubersoum.

Keerthana said: (Jan 20, 2018)  
Potato is a modification of stem or simply underground stem modification.

Kigundu Daniel said: (Oct 3, 2018)  
I think it is not a stem tuber because tubers swell from underground but not from the shoot.

Bincy said: (Jan 23, 2019)  
Potato is an example for underground modification of stem. It develops by the swelling of the tip of stolon (slender lateral branch from the base of the stem). It stores large amount of food, mainly starch.

RAUSHAN Kumar said: (Apr 3, 2019)  
Potatoes grow underground, but the part we eat is not a root. It is a an underground stem called a tuber.

Tani said: (Apr 3, 2019)  
It is a stem vegetable. The potatoes grow on underground stems, called stolons. You can know potato tubers are actually thickened stems because they have buds that sprout stems and leaves. Roots don't do that.

Pavanireddy said: (Sep 29, 2019)  
The potatoes grow on underground stems called as stolon. So, it is tuber.

And also potato is a stem modification form.

MOHAMMED said: (Jul 22, 2020)  
I agree with the given answer.

Kaggwa Andrew said: (Nov 13, 2020)  
No, It is not called as a root tuber because anything to be called a tuber has to be growing from the ground.

Jimmy said: (Feb 19, 2021)  
Why are sugarcane not regarded as stem tuber yet they store food? Explain.

David Ochieng said: (Dec 26, 2021)  
First, there are two types of potatoes.

Irish potatoes which are stem tuber and sweet potatoes which it is root tuber.

Pranjal said: (Jan 5, 2022)  
How can a potato be a shoot it grows opposite to gravity (negative geotropic) which is a feature of roots only?

Please explain me...

Musaazi Jb said: (Mar 31, 2022)  
Why a sugar cane is not a stem tuber? Anyone explain me in detail.
